lookup_table_cells
Look up cells in a table a page at a time, returning cell IDs and row IDs alongside their values. Pass match to find particular rows and columnNames to limit the columns. The result’s page says how many rows there are; pass page.nextOffset to continue. Essential before setting linked identifiers, linkCell values, oneMany references, or formula expressions. For linked identifiers: use the returned rowId to build {“linkedTableId”: tableId, “linkedRowId”: rowId}. Returns rows with { rowId, cells: [{ cellId, columnName, columnType, value, isIdentifier }] }.
